8 - y - 4(2 - 3y) = 24 + 3y
8 - y - 8 + 12y = 24 + 3y
Combine like terms:
12y - y + 12 = 24 + 3y
11y + 12 = 24 + 3y
Subtract 3y from both sides:
11y + 12 - 3y = 24
8y + 12 = 24
Subtract 12 from both sides:
8y = 12
Divide by 8:
y = 12/8
y = 1.5
Ответ: y = 1.5
8 - y - 4(2 - 3y) = 24 + 3y
8 - y - 8 + 12y = 24 + 3y
Combine like terms:
12y - y + 12 = 24 + 3y
11y + 12 = 24 + 3y
Subtract 3y from both sides:
11y + 12 - 3y = 24
8y + 12 = 24
Subtract 12 from both sides:
8y = 12
Divide by 8:
y = 12/8
